标签： android android-layout android-intent onclick onitemclicklistener

任何人都可以举例说明/帮我看下一个活动的onclick按钮。我的自定义列表视图包含文本，按钮和滚动索引..我正在点击按钮问题..我尝试了3天但没有用..如果任何人说我怎么做使用onitemclickchildview（按钮（btnlist） ..正如我在一些文档中看到的那样，他们告诉listview是父级和内部列表视图项/内容/数据  是孩子..我希望儿童按钮（btnlist）onclick。请帮帮忙..先谢谢你。

我不确定你的代码，它太繁琐了。但我以前遇到过同样的问题，我解决了如下问题。在适配器中，您需要为该按钮设置on click侦听器并为其添加标签。

holder.btnList.setOnClickListener(((MyActivity) context));

其中context是您传递给适配器的上下文，而MyActivity是要处理点击的任何活动。因此，当您单击该按钮时，将调用点击侦听器上的MyActivity。如果要传递任何数据，还可以向持有者对象添加标记。然后在MyActivity中实施onClickListener。您可以在MyActivity中处理所需的任何事件。如果您有任何疑问，请发表更多疑问。

答案 1 :(得分：0)

holder.btnList.setOnClickListener(new OnClickListener(){
     @Override
     public void onClick(View v){
     //youre code

     }
);
